AP Biology Meiosis Essay

myosis is the operation in sexually reproducing organisms where stalls divide. The cellular telephones produced during myosis have i-half the chromosome number as the original cell. There are cardinal cell divisions in reduction division, meiosis l and meiosis ll. These cell divisions produce 4 hapolid daughter cells. Haploid cells shoot only matchless set of chromosomes, which is written as n. Meiosis consists of nine phases. In meiosis the interphase l the chromosomes replicate and the central body duplicates in one diploid cell. Diploid cells have two sets of chromosomes, they received one from from each one parent. During prophase l the atomic envelope fragments and spindle microtubules form betwixt the centrosomes. Homologous chromosomes twosome to make two baby chromatids. This is called synapsis. Chromatids of homologous pairs exchange segments when they cost ringer all over. At metaphase l, the pairs line up on the metaphase cuticle. Microtubules from one perch attach to the kinetochore of one homologous chromosome, dapple microtubules from the other pole attach to the kinetochore of the other pair. During anaphase l the microtubules bum shorter pulling the homologous pairs towards opposite poles. At telophase l two haploidic cells form exactly the chromosomes are liquid double. Meiosis ll separates the sister chromatids. During prophase ll the sister chromatids in each cell begin moving towards the equator. At metaphase ll the chromosomes align on the metaphase plate in each cell. The process of anaphase ll pulls the sister chromosomes to opposite poles in each cell.

During telophase ll each cell forms! a nuclei and cytokinesis splits the cells apart. Four genetically different haploid cells are produced. Independent assortment is differences amidst the genes. diversity can occur in meiosis when the chromosomes cross over and during stochastic fertilization. Random fertilization is when a gamete from the mother unites with the haploid from the father to produce... It was quite informative, but you should fix the layout of your text because it is painful to read it when the distances between the sentences is big. You should also have a windup and introduction.
